Running several times an application

hi, I am beginner in JAVA programming.
I have done a main class with methods using variables. On the other hand I have an interface vers the application's user can change those variables. How can I run several times my main class, each time the user changes a variable?
Thanks for your help and hello to everybody from the bourbon Island !(Reunion Island)

Hmm , you usually don't call your main-method multiple times...
Could you post your code, that should make thing more clear...

Have a bash script run every time an application is opened.

Hi,
On my Arch box I would like to have a bash script run every time a certain application is opened from the menu. I would prefer a delay of a 5 - 10 seconds after the program opens if that is possible. Could someone please let me know if and how I can achieve this?

Problem is, OP wants the "meat" of his script to run after the program, which would mean putting it after the exec. But AFAIK, anything after the exec will be ignored. You could call another script to run in the background before the exec, but that seems hackish.

Query that becomes slower and slower when runned several times

Hi everybody,
I have an issue with one querie...
I have a select that is a join between 3 subqueries, 2 of them are using a function with pipeline.
When I run this query it work fine.
* First run lasts less than 1 sec.
* Second run lasts less than 1 sec.
* Third run lasts 2 sec.
* Fourth run lasts 2 min.
* Fifth run lasts 10 min.
* ... and then worse an worse...
Of course, I always use same bind variables and data within the database does not change.
I looked at the execution plan that seems to be the same for all the runs.
The problem is during the Execute phase :
for the first run :
call count cpu elapsed disk query current rows
Parse 1 0.00 0.00 0 0 0 0
Execute 1 0.20 0.20 0 1215 0 0
Fetch 3 0.12 0.14 0 246 0 19
total 5 0.33 0.36 0 1461 0 19
Misses in library cache during parse: 1
Misses in library cache during execute: 1
Optimizer mode: ALL_ROWS
Parsing user id: 66
for the fifth run
call count cpu elapsed disk query current rows
Parse 1 0.01 0.01 0 0 0 0
Execute 1 95.29 100.96 0 1215 0 0
Fetch 3 0.27 0.39 0 246 0 19
total 5 95.57 101.36 0 1461 0 19

I didn't find dynamic sampling during the execution plan.
All subqueries are very stable in time.
When the join query starts to have a strange behavior, subqueries are still very perfomant !
If I flush the shared pool, the problem disappear and the cycle restarts...
1) any idea of the root cause of the issue ?
2) is there a solution (with hint for instance) for not recording the query inthe shared pool ?
Thanks in advance...
The query is :

Hi Nikolay
Concerning point 2, the database seems perfectly OK and I encountered an issue only with this query :-(
The database is hosted on a dedicated server and I am the only one user. Moreover the issue is reproducible as I want... Very strange for me...
I am very interested on a method to check waits and more precisely IO waits. Can you describe me a procedure ?
The only one thing I can produce is the tkprof output focused on the fifth run that is very long...

Urgent Help please ---deploying several times an application

Hi everyone,
I am trying to deploy an EJB (TestEJB, remote interface is Test) component
into weblogic 6.1. All the files related to TestEJB are in the package com.myApplication.test.
In the config.xml, the tag
<Application Deployed="true" Name="Test" Path=".\config\mydomain\applications\test">
<EJBComponent Name="test" Targets="server1" URI="test.jar"/>
</Application>
is written only once. Initially first time when I start the weblogic server,
the test.jar will be deployed successfully without any error. When I stop the
server and check the config file, there will be two <Application> tags
for test.jar. I do not know how this tag is added once again.
So when I restart the server now , I get the following error :
Unable to deploy EJB: Test from test.jar:
Unable to bind a cluster-aware stateless session EJBObject to the name: ejb.com.
myApplication.test_EO. Please ensure that the jndi-name in the weblogic-ejb-jar.x
ml is correct. The error was:
javax.naming.NameAlreadyBoundException: Can't rebind anything but a replica-aware
stub to a name that is currently bound to a replica-aware stub; remaining name
<<no stack trace available>>
>
<Nov 11, 2003 1:49:21 PM EST> <Error> <Management> <Error deploying application
.\config\mydomain\applications\test: java.lang.reflect.UndeclaredThrowableExcept
ion>
Again when I start the server, one more <Application> tag will added for test.jar.
Very weird !!!
I do not know why this <Application> tag for the componet test.jar is getting
added each time when I start the server. How to avoid it ?
Only first time when I start the weblogic server, I do not get this error
because there will be only one tag in the config file. But when I stop
the server, the config.xml will be updated with one additional <Application>
tag for test.jar. This keeps repeated each time when I restart the weblogic
server.
Please suggest me how to get rid of this tag getting added repeatedly to the
config.xml.
My weblogic-ejb-jar.xml for test.jar :

I'm not following you anymore.
The only thing in your applications directory should be test.jar. Is
that the case?
When you boot the server, it will add an Application to the domain
configuration with a path of applications/test.jar.
If you're still having problems, can you show me your config.xml, or at
least the Application entries.

<Application> tags from the config.xml.
I removed all such <Application> tag for the test.jar
Next, if you're trying to deploy to the applications directory, then
it
should be applications/test.jar, not applications/test/test.jar
I think the server believes you have 2 different applications, and
that's causing problems because they both have the same JNDI name.
I removed "test" from the path.
But still I am getting the error. The main reason for this error is, When
I STOP the server, it is adding the tag <Application> for test.jar. (god
only know why it is adding this tag) and this will be repeated each time when
i STOP the server.
Obviously, when i restart the server, the server will come accross multiple
<Application> tag for this test.jar. That's why it gives error "javax.naming.NameAlreadyBoundException:
Can't rebind anything ....."
All my question is why server is adding this tag <Application> to test.jar
thanks.

My track pad highlights applications and files and then opens them without my doing anything. I run MacKeeper and having run the scan several times only get cleaning issues (5 -). Any ideas as MacKeeper Kromtech have not responded to my calls nor email.

Folks
I run an iMac. Today for some reason when I run the cursor across the screen applications and files are highlighted and then opened without me doing anything (no clicking etc) In fact print at times opens. As far as I can tell I have not changed any settings except to open firewall.
I run MacKeeper and when I run a scan only a few cleaning items open. Safe and fast are as they should be. I run fix. If I again run the scan I get a few more but different claeing items to fix.
I have rung MacKeeper several times without getting through. The occasion I did get through the bloke said he could not help and passed me to a higher authority. Needless to say the line dropped out after 30 minutes waiting.
As it is the weekend and I do not live near an Apple store I am quite keen to get the problem identified and fixed so I can continue working.
Your assistance please.

Remove the "MacKeeper" scam product as follows. First, back up all data.
"MacKeeper" has only one useful feature: it deletes itself.
Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.
IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.
In the Finder, select
Go ▹ Applications
from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the functional components of the software will be deleted. Reboot.
☞ Quit MacKeeper before dragging it to the Trash.
☞ Don't empty the Trash. Let MacKeeper delete itself.
☞ Don't try to drag the MacKeeper Dock icon to the Trash.

[[Firefox is already running but is not responding]]
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

IMac (2008) OS10.6.8 - Main menu freezes when running more than one application at a time. Apple and 3rd party applications - all freeze the main menu. Safe mode seems to work OK. Tried repairing permissions - didn't work.

For the past 60 days I've experienced Main Menu freeze when running more than one application at a time. iPhoto, Preview, Text Edit, Epson Scan, Firefox and Thunderbird are the apps I use almost daily. No matter what I do, when more than one is running they will freeze the Main Menu (top of the screen). I've tried booting is Safe Mode and I don't seem to have a problem. I've tried several suggestions from repairing permission (DiskUtility) to eliminating specifis login items. Nothing works. I've posted this issue on the Apple forum several times and no one else has experienced this problem. I hesitate to take my iMac to the Apple Store or a private Apple repair service until I've exhausted all of my options. Do I have any more options?

Question: Everytime an app crashes I have the option to report it to Apple - which I usually do. But I've NEVER reported a Main Menu freeze because it never asks me to
There's really no need to submit to Apple, it's just a round file cabinet on the other end, especially with 10.6 or earlier.
This sure sounds like a resource problem...
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab, are there a lot of Pageouts?

My iMac running 10.10.2 keeps crashing several times a day. It does a automatic restart and gives me a option to send in a report. Any ideas what might be causing this?

My iMac does an automatic restart several times a day. It gives me a option to send in a "panic" report. This happens randomly during the day and night. Any idea of anything new that might be causing this? I am up to date on all applications.

Mac users often ask whether they should install "anti-virus" (AV) software. The usual answer is "no." That answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions.
It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to take control of it remotely. That threat is in a different category, and there's no easy way to defend against it. AV software is not intended to, and does not, defend against such attacks.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't been checked for security by Apple unless it comes from the App Store, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, not machine behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a padlock icon in the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial AV or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It can be as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

I can't find the mac app store on my imac. i am running snow leopard, and i have run "update software" several times. what's up?

I am trying to upgrade to Lion. I need to go through Mac App store to buy it. I need to get the Mac App store icon in my dock. I have run Update Software several times, trying to get the Mac App store onto my iMac, but with no luck. It doesn't show up in the dock, it doesn't show up in Finder under Applications, and it doesn't show up when I search in Searchlight for App Store, Store, Mac App Store, etc. What am I doing wrong?

I am running snow leopard
James....
You arne't necessarily doing anything wrong.
Install the Mac OS X 10.6.8 Update Combo
That should reinstall the App Store for you.
Restart your Mac after the combo is finished installing.
You should see the App Store icon in the Dock and be able to access from your Apple menu also.
Make sure your Mac meet's Lion's requirements

How to run a query several times?

Hi all,
Anyone has a clue for the following situation:
We have made a query (on the web) with several characteristics and key-figures. One of the characteristics has unique values that occurs only once (something like numbers for documents in R/3). The query was build with only one user-input variable based on this characteristic. The query was build especially for printing and fits exactly on a A4-paper.
We would like to give the end-user a tool in which he/she can store several values for the characteristic. On the basis of these stored values the system has to run the query several times.
Something for the Reporting Agent or is there an other solution?
Thanks in advance,
Henk.

hi Henk,
'control query' in few words is to filter data with combination of characteristic value.

Control Query for Pre-calculating Web Templates
Definition
A control query is a help query that you execute before you execute the queries in the Web template, and use the result to parameterize the Web template.
Use
You can specify a control query as significant information in the Reporting Agent settings for a Web template. When you specify a control query, the system does not pre-calculate the Web template itself, but a number of filtered views from the Web template.
We particularly recommend this procedure when wanting to calculate several Web templates only distinguished by their filter values in one swoop.
Using a control query in particular allows you to formulate complex selection criteria for the data to be pre-calculated.
Pre-calculate only the TOP50 customers, whose data is frequently requested, for example.
Structure
A very simple query, which contains exactly those characteristics in the drilldown in the rows according to which the Web template will be filtered, is particularly suitable as a control query. Every row in the table that a control query delivers, subsequently serves as a dynamic filter for the Web template views.
The respective combination of characteristic values is used as a filter for the Web template Data Provider for each table row. The background run produces pre-calculated data records, in actual fact one data record for each table row that delivers a control query.
If a characteristic does not appear in a view, the filter value is ignored.
In addition, you automatically get only those filter value combinations, for which data exists in the InfoCube used to define the control query.
Example
A typical application of this approach for pre-calculating a Web template is with cockpit applications, since they are controlled mainly through selection lists and no real OLAP navigation is necessary.
You can also use a control query for filtering when pre-calculating Crystal reports queries. You can find additional information under Defining Crystal Reports Queries Settings.
